Specification forming part of Letters Patent No. 138,728, dated May 6,1873; application filed April 26, 1873.

When inposition the foot of the support rests against the stop, usuallyprovided .in ordinary desks, to prevent books and other articles fromslipping off.

The importance of an economical and simple support as an attachment todesks, especially school-desks, has been long felt, and in my device Ipropose to furnish such an article as will fully meet the requirementsin the case.
